But that just gives you "jcc/jcc.lib". It's the path that's interesting.
I see some code in distutils.cygwinccompiler that seems to point the
way. In the twisted world of Distutils/Setuptools, the way you address
issues like this is to generate a subclass of, in this case,
distutils.cygwincompiler.Mingw32CCompiler, and then monkeypatch
disutils.cygwincompiler so that your subclass becomes the actual class.
In this case, the subclass would override the link() method, and extend
objects with the appropriate filename:
Here's a direct quote from that code:
# we want to put some files in the same directory as the
# object files are, build_temp doesn't help much
# where are the object files
temp_dir = os.path.dirname(objects[0])
# name of dll to give the helper files the same base name
(dll_name, dll_extension) = os.path.splitext(
os.path.basename(output_filename))
# generate the filenames for these files
def_file = os.path.join(temp_dir, dll_name + ".def")
[...]
objects.append(def_file)
So I'd do the same for jcc.lib:
lib_file = os.path.join(temp_dir, dll_name + ".lib")
# now make sure setuptools knows to include it
objects.append(lib_file)
And add
# generate .lib file for the .pyd
extra_preargs.append("-Wl,--out-implib,%s" % lib_file)
to the "extra_preargs". That should create jcc.lib in the correct
place, but that seems to be the only way of getting my hands on the
generated location, and of telling setuptools to put that file in the
egg.
On the other hand, it should work :-). I'll try it tomorrow.
